| Research Abstract |
Plasmacytoid dendritic cells(PDC) play a pivotal role in host defense against viruses by their robust production of type I interferons. They exclusively express TLR7 and TLR9 which is a sensor to viral and microbial DNA and RNA, while it has still been unclear in the mechanisms in the augmentation and regulation of cytokine productions. In this research, PDC-TREM, a specific surface receptor on activated PDC surface, has been investigated. PDC-TREM is associated with PlxnA1, a ligand for Sema6D, and gives signals through adaptor molecule DAP12, resulting in the regulation of type I IFN production.
